XML Sitemap for more than 50k pages.

Actually, my site has more than 50k pages and all pages are dynamic. I want to create xml sitemap. Can somebody tell me any XML sitemap generator tools that can create sitemap more than 50k pages? Please, please… suggest me, if you know any tools.

If it takes 5-6 hours for 30k pages, it is most likely a server issue since A1SG can crawl much higher number of pages. Remember A1SG is not a database solution, i.e. something that just reads a database, it actually crawls your website. (And if you are using e.g. a video sitemap preset, it will also have to crawl some external pages as well.)
